Regular pieces. It refers to parts that are often used, such as high frequency, large loss of equipment and cheap univalent, such as vulnerable parts, large consumption parts, and key equipment, and so on.
(2) very spare parts. Parts with low frequency, small stop loss and expensive unit price can be divided into plan purchase parts: purchase parts in advance for short-term reserves according to repair plan, purchase items at any time before repair, or parts that are used immediately after manufacture.

At present, manufacturers, distributors, and contractors in the U.S. HVAC industry are very concerned about the development of VRF equipment and applications in the U.S. market. For other countries such as China and Japan, the technology has reached saturation in the market. However, in the United States, the product market is still growing and its current share is only 4%. Industry experts hope that VRF products will have more market share in the coming years.
This year, manufacturers have made a lot of efforts to continuously promote the development of VRF in the North American market. One of the major events in November was that Daikin announced that VRF entered the American home industry. This is not only a brand effect, but will also bring about corresponding practical system applications. According to the company's announcement, brands such as Daikin, Goodman, and Amana will be "landed."
Eighteen months ago, Carrier’s joint venture with Toshiba announced that its VRF products will enter the North American market. Meredith Emmerich, general manager of Carrier's VRF business, said: "Although VRF is still a new thing for the North American market, Toshiba Carrier's products have been manufactured and sold globally for the past 10 years. With the addition of VRF products We will be able to provide a full range of solutions for numerous construction projects. Due to the design flexibility and high efficiency of the VRF system, we believe this product will achieve better development in the future."
As a newcomer to the VRF market, Trane has released a series of VRF commercial products and services, which are mainly used for historic buildings, apartments, well-furnished commercial properties, and theaters. Mike Smith, senior marketing manager of commercial products for the US Heating and Air Conditioning Division of Mitsubishi Electric, said: “In the past five years, the United States Department of Energy (DOE), the American Association of Air Conditioning, Heating, and Refrigeration (AHRI) and ASHRAE have passed the amendment of policies and regulations to clarify The high energy efficiency of ducted and VRF systems will enable this technology to continue to be recognized and applied as one of the major technologies in the HVAC industry."
Globally, Fujitsu has been selling VRF products since 2001 and has entered the North American market for two years. Brendan Casey, Commercial Product Manager of Fujitsu America, said: “We are constantly promoting the growth of this product. This product can meet various needs such as environmental protection, high efficiency and comfort.†Daikin pointed out that future development will fully demonstrate the entire life cycle of VRF products. The advantages.
For distributors and contractors, the change in the VRF market is an increase in the demand for corresponding training and services to ensure the successful application of products. Supply chain and customer training have become one of the priorities of manufacturers. For this reason, many VRF manufacturers have been dedicated to training, and some companies continue to add new training opportunities. Take Fujitsu as an example, it requires all designers and installers to attend a 3-day training course at their training center.
Casey pointed out: "Although the installation of the VRF system is not difficult, there are still some specific rules, such as the calculation and consumption of refrigerants, which are slightly different from the operation of other standards. By participating in such training, contractors can have less Take detours and ensure compliance with installation guidelines. Recently, we have also added special heat recovery VRF training."
In addition to formal classroom training, Daikin also introduced a new Learning Management System (LMS) last year that included more than 350 independent training courses. LeeSmith said: "Daikin's training customer courses cover all the contents of VRV and VRF technology. Every year, we will increase 20 training points and carry out formal classroom training."
Carrier Corporation uses its Carrier University in New York State to conduct online and offline training. Emmerich pointed out: "A contractor needs to complete all courses in VRF training and certification, including product, control, design, application and technical services. Technical service training includes installation, start-up, commissioning, operation, maintenance and troubleshooting. In addition, the contractor It is also important to learn to use software tools that not only help design, but also facilitate the smooth start-up and troubleshooting of VRF systems. This is very important."
Mitsubishi Electric Corporation requires that the contractor must obtain all local and state government certifications. At the same time, contractors are encouraged to participate in factory training to ensure that they provide their customers with the best service. What will happen to the future development of VRF in the United States? As an alternative technology, the flexibility and adaptability of the system make its application development only one way, that is, continue to grow. Casey pointed out that in 2003, when VRF technology first entered the United States, the crude oil price was about 25 US dollars per barrel, and the market would not be interested in the VRF at all. 2005 was a big turning point, when crude oil prices had soared to $141 a barrel.
Another difference from the early years of VRF development is the limitation of the length of the system pipeline. According to LeeSmith, in 2004, the pipe network was limited to 1,000 feet, and in 2013 it has increased to 3,280 feet. MikeSmith said: "The VRF regional system has developed very well and has become a mainstream product. The rest of the world has already approved this technology and North America is catching up. Since the Mitsubishi Electric VRF product entered the North American market in 2003, the product has grown. To 50 million US dollars. With the rapid development of the North American HVAC market, VRF regional technology will continue to develop with the introduction of new energy efficiency regulations."
